Answers to common product and project questions.
How do I confirm this fits my car?
Every WPM half cage is built for non-sunroof cars. Email your year, chassis, and options before you order and we will answer directly. Ask a fitment question.
Does install require drilling, welding, or trim removal?
We recommend welding the cage in. Bolt-in base plates are included as well; using them usually means drilling through the vehicle. Professional installation is heavily recommended.
What finish options are available?
Standard finish is satin black powdercoat. Custom is any color from Prismatic Powders. Select Custom, type the Prismatic code and color name on this product (for example, PSS-11632 Porsche Speed Yellow), then add to cart. Do not put the color on the order note. Standard and Custom are the same price.
How long is transit after it ships?
Once it ships, transit is usually 3–5 days, subject to change.
Can I cancel my order?
Yes, until the cage is powder coated. After powder coat, the order cannot be cancelled.
Can WPM install it?
Yes. Professional installation is heavily recommended, and WPM installs in-house. Ask about WPM installation.
Can I run this in my racing series?
All WPM parts are sold for off-road use only. Reach out with your application and we will walk you through how our products can meet your ruleset. Contact WPM.
